Technical Field

The invention relates to the technical field of kitchen appliances, in particular to a cleaning machine for cleaning dishes, fruits and vegetables.

Background

At present, the conventional dish washing machine on the market generally comprises a box body and a spraying device arranged in the box body, wherein the spraying device is used for drawing water at the bottom of the box body into a water spraying part and spraying the water into a washing cavity to wash dishes.

The volume of the washing chamber of most dishwashers is fixed and cannot be changed according to the quantity of the washed dishes. When the quantity of the tableware to be cleaned is less, the tableware is placed in a larger washing cavity for cleaning, so that the cleaning effect is influenced, and the waste of water resources is caused. In addition, for some dish washing machines with large capacity, users are used to store the tableware in the dish washing machine after the dish washing is finished, in this case, if the tableware used in each meal is small, the stored tableware needs to be communicated for cleaning at the next time of cleaning the tableware, and waste of water and electric resources is caused.

In order to solve the above problems, chinese utility model patent No. CN208973719U, a multifunctional dish washing machine (application No. CN201821019731.0), chinese utility model patent No. CN208973725U, a variable volume dish washing machine (application No. CN201821019541.9), etc. all disclose a structure for cleaning dishes in different states by arranging a partition plate, wherein the partition plate is horizontally arranged in a washing chamber to form a first use state for cleaning dishes on a lower dish rack, and the partition plate is taken out from the washing chamber at the present time to form a second use state for cleaning the dishes on the upper and lower dish racks at the same time.

The structure can adjust the size of the cleaning space according to the number of the tableware to be cleaned, thereby saving water and electricity. However, the partition board can only be completely in the washing cavity or completely taken out of the washing cavity, so that the partition board is required to be inserted and pulled out according to the requirement when the washing machine is used by a user every time, and the operation is very inconvenient.
